找不到類別異常 - Maven Eclipse

-1

我已經使用Maven創建了dyamic Web項目。我已經使用這個（https://github.com/Codearte/jfairy）假數據生成器插件爲行家在我的pom.xml像如下：找不到類別異常 - Maven Eclipse

<dependency> 
    <groupId>io.codearte.jfairy</groupId> 
    <artifactId>jfairy</artifactId> 
    <version>0.5.3</version> 
</dependency>

但我得到的錯誤，如如下：

於是就諮詢我它。

嘗試清理構建應用程序 – ravthiru

你可以檢查jar是否實際下載？ – root545

轉至項目屬性>部署彙編>添加> Java構建路徑條目> maven，應用 –

Eclipse maven集成工作不正常。你可以到項目目錄並運行此命令：

mvn eclipse:clean 
mvn eclipse:eclipse 
mvn install

換句話說每次改變時間的pom.xml你更好的殼牌使用

mvn eclipse:eclipse

。

嗨Vahid，我試過這個，但仍然得到了同樣的錯誤。 –

@ChetanNakum你確定jfairy依賴解決嗎？ jar文件存在於你的路徑中？我搜索並找到這個鏈接：http://snacktrace.com/artifacts/io.codearte.jfairy/jfairy/0.5.2/io.codearte.jfairy.Fairy – vahid

是的，我仍然解決jfairy依賴。 http://prntscr.com/dguhdo –
